get_valley_polygon

Create vector/polygon representation of valley without holes from raster mask

internal

Provides tools to automate the morphological delineation of
riverside urban areas based on a method introduced in Forgaci (2018)
<doi:10.7480/abe.2018.31>. Delineation entails the identification of
corridor boundaries, segmentation of the corridor, and delineation of
the river space using two-dimensional spatial information from street
network data and digital elevation data in a projected CRS. The
resulting delineation can be used to characterise spatial phenomena
that can be related to the river as a central element.
